We must not store references to selected devices as they may be
hot-removed. Instead, look up the device based on its tag right before
using it. If the device disappeared, throw an interrupt and disconnect.

According to the LSI spec, the reset value of dcmd, dstat, and ctest2

are surely more discrepancies, this is just another increment.

Once the I/O completion callback returned, aiocb will be released by the
controller. So we have to clear the reference not only in
scsi_write_complete, but also in scsi_read_complete. Otherwise we risk
inconsistencies when a reset hits us before the related request is
released.

exec.c has a comment 'XXX: optimize' for lduw_phys/stw_phys,
so let's do it, along the lines of stl_phys.
The reason to address 16 bit accesses specifically is that virtio relies
on these accesses to be done atomically, using memset as we do now
breaks this assumption, which is reported to cause qemu with kvm
to read wrong index values under stress.

Unfortunately the bsd emulation still uses the old mmap implementation,

updated version of an old patch
http://xenon.stanford.edu/~eswierk/misc/qemu-linuxbios/qemu-piix-ram-size.patch
that together with
http://www.mail-archive.com/linuxbios@linuxbios.org/msg02390.html
(which is already in coreboot trunk) allows coreboot to autodetect the amount of RAM within qemu/kvm from a register in i440 northbridge.
The message on the old patch states:
Unfortunately the current version of qemu does not set these
registers, but I have patched qemu so that it emulates the i440 more
faithfully in this regard.

With three different make binaries I have available, configuring a
pristine QEMU tree and attempting to make gives the cryptic:
Makefile:27: *** missing separator. Stop.
This patch fixes it (presumably because it makes the output of
`set-vpath' be an empty string, rather than a bit of whitespace), but I
don't understand why this hasn't been a problem for other folks before.

Currently the commandline to create a virtual-filesystem pass-through between
the guest and the host is as follows:
#qemu -fsdev fstype,id=ID,path=path/to/share \
-device virtio-9p-pci,fsdev=ID,mount_tag=tag \
This patch provides a syntactic short-cut to achieve the same as follows:
#qemu -virtfs fstype,path=path/to/share,mount_tag=tag
This will be internally expanded as:
#qemu -fsdev fstype,id=tag,path=path/to/share, \
-device virtio-9p-pci,fsdev=tag,mount_tag=tag \
